Repeater with Object as Value

Aug 15th, 2005

I am trying to iterate through a hashtable that i have populated with objects using the repeater control.
For each iteration i wish to output the values of properties of the objects I am populating the hashtable with.

For example: -

Class SomeClass 
{ 
public String myProperty1 
public String myProperty2 
 
    public SomeClass() 
    { 
        this.myProperty1 = "hello"; 
        this.myProperty2 = "goodbye"; 
    } 
} 
 
 
Class TestSome 
{ 
    public Hashtable myHash    = new Hashtable(); 
 
    public TestSome() 
    { 
        myHash.Add("key1", new SomeClass()); 
    } 
 
}
 

Class SomeClass 
{ 
public String myProperty1 
public String myProperty2 

    public SomeClass() 
    { 
        this.myProperty1 = "hello"; 
        this.myProperty2 = "goodbye"; 
    } 
} 


Class TestSome 
{ 
    public Hashtable myHash    = new Hashtable(); 

    public TestSome() 
    { 
        myHash.Add("key1", new SomeClass()); 
    } 

}

In the webform codebehind: -

this.myRepeater.DataSource = myTest.myHash; 
this.myRepeater.DataBind();

this.myRepeater.DataSource = myTest.myHash; 
this.myRepeater.DataBind();

        <%# DataBinder.Eval(Container.DataItem, "myProperty1") %> 
         

        <%# DataBinder.Eval(Container.DataItem, "myProperty2") %> 

    </asp:Label> 
    </DIV> 
    </ItemTemplate> 
</asp:repeater>

I found the problem

I should be using:

Help with Code Tags

C# Syntax (Toggle Plain Text)

 
<%# ((SomeClass)Container.DataItem).myProperty1 %>

instead of the 'Databinder.Eval' statement. I can then repeat this statement changing the propery value to show each of the properties I want to show.

It works great now.
